IMPROVEMENT-IN PEN-HOLDERS.

Specification forming part of Letters Patent No; 200,061, dated February 5, 1878 application filed Q January 14, 1878.

To all whom it may concern: I I I I 7 Be it known that we, Josnrn HOFFMAN and OLAns W. Z BOMAN, both of the city of New York, in the county of New York and State of New York, have invented cer- I art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to that kind of penholder in which the nib and the outer tube or barrel are formed in one piece, and are brought to the shape of a pen-holder by coiling the piece into the form of a tube with the nib inside.

In this kind of pen-holder trouble has arisen from the fact that the insertion of the pen into its place in one .end of the holder and the penhandle into its place in the other end of the holder is very liable to cause the tube to spread and open, especially at its nib end. Pen-holders of this kind heretofore made have also required in their construction quite a large quantity, by weight, of material.

It has been our object to produce a penholder which will not spread or open, and which at the same time shall contain a less weight of metal than has heretofore been the case with pen-holders of the kind referred to.

To this end we form at some proper or convenient point on that part of the blank that forms the outer barrel or tube a tongue, which, whenthe blank is coiled up in pen-holderform, can be folded into or engaged with a notch, slot, or recess formed at a corresponding point in the inner barrel or nib, so as to lock the two together insuch manner as to prevent expansion of the pen-holder, while leaving the inner tube or nib free to yield to permit the insertion of a pen.

The blank at the nibbed end is, of course, of the full width required to form the two folds of the coil which constitute the outer tube or barrel and the inner nib. It may be, and preferably is,of the same width throughout its entire length, so that the blank, when coiled,

will have'a double thickness from end to end of the pen-holder. The blank may, however, be of less width below the nibbed portion, as shown for instance, in McGills patent, No. 154,801, of September 8, 1874'.

The nature of our improvement and the manner in which the same is or may be carried into effect will be understood by reference to the accompanying drawings, which we will now proceed to describe.

Figure 1 represents in plan a sheet-metal blank for a pen-holder, embodying our invention in its preferred form. Fig. 2 is an elevation.

of the blank after having been coiled into the shape of a pen-holder, with the locking-tongue still unbent. Fig. 3 is an elevation of the same with the tongue bent down upon the inner barrel or nib-piece. Fig. 4 is a section of the pen-holder on-an enlarged scale on the line 00 m, Fig. 2.

Of the blank shown in Fig. 1, thepartAforms the inner barrel or nib-piece, and the part B the outer barrel, of the pen-holder. At the top of the vertical outer edge of part B is a tongue or strip, a, and in the top edge, intermediate between the twoparts A B, is a notch, b, which, when the blank is coiled, comes directly opposite the tongue a. The blank, by suitable mechanism, is coiled into the form of a penholder, having walls composed of two thicknesses of metal, as shown in section in Fig. 4.. When so coiled the tongue at on the outer fold is brought opposite to the notch b of the inner fold. The tongue a is bent down over the top edge of the inner fold, so as to engage the notch 12 and overlap the said inner fold. The overlapping takes place at a point on the periphery corresponding to the point 0 in Fig. 4. The outer edge d of the outer barrel is thus looked to the inner barrel or nib-piece in such manner as to be prevented from expanding, while the inner barrel or nib is left entirely free and unfastened along its edge e, and can thus freely yield to the insertion of the pen between it and the outer fold.

A very slight indentation in-the edge of the inner fold is sufficient to insure the engagementtherewith of the tongue. It is also manidicated: at f in Fig. 5. spending slot, 9, ismade in the: blanlg so that V ters Patent, is-

' fest that the position of the lockingdeviees may admits of a better finish to the pen-holder.

In lieu of putting the tongue at the top of the blank, it can be placed on the 'side,'a's in-' In this case a conewhen the blank is coiled up, as in'Fig. '6; the tongueniay beinserted through the slot, and

' then bent over upon the innerbairel, as shown in Fig. 7. which is a section on an enlarged scale on'line y y, Fig. '6.

V ferred manner of carryingthe same'into ef fect, we state, invconclusion, that we do not 7 limit ourselves :to the particular details of construction herein specified; but 7 7 'What we claim, and desire to secure by Let- 1. A pen-holder formed of a single piece of sheet metal'coiled into a pen-holder, with outer barrel andinnernib, as described, withatongue on the one part engaging the other partin such 7 r V manner as to prevent the expansion of the outerbarrel at the nibend, while leaving the nib free to yield. V r V r 7' 2; A pen'holder formed of a single piece of sheet metal coiled into a scroll or volute, with walls of double thicknessthroughout its length; 'the inner fold (constituting the nib-piece) being connected with the outer fold by a tongue or locking-piece to prevent said outer fold from spreading, substantially as set forth.

In testimony that we claim the foregoing as 7
